TO Ann WHOM IT MAY CONCERN:

Be it known that I, F. B. MORSE, of New Haven, inthe county of NewHaven, and State of Connecticut,

have invented a new Improvement in Stump-Joint for Carriages} and I dohereby declare the following, when taken in connection with theaccompanying drawings, and the letters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in

Figure 1,a perspective view of thejoint closed, and in Figfire 2 a. topview of thejoint open. 7 i This invention relates to an improvement inthe stump-joint for which Letters Patent were granted to me, July 28,1868, but is alike applicable to otherjointsin which the two stumps arejoined by a tongue and the invention consists in forming notches or anuneven surface upon the meeting-end of one stump, and a correspondingsurface upon the other stump, so that, when the joint is open, so thatthe two ends meet, the irregular surface of one will mesh into thecorresponding irregularities of the other, so as to strengthen the jointin that position, and prevent the shackling of the joint.

In orderctothe clear understanding of my invention, I will fullydescribe the same as illustrated in the accomp'hnying drawings.

Ayis the one ,part, B the othe'ri the two partsjoined by a piece ortongue, 0, to which each part is pivoted at a andrl. v i p In Lmy patentbefore referred to, which embodies the construction of a joint of thesethree parts, when the joint is open, as in fig. 2, the back ofthe recessin each partbears against the edge of the piece or tongue 0, as a-guidoto bring it to und asa support to sustain it in the proper position. i

By constant use, the parts are liable to more or less wear, and suchwcar' would tend to loosen the joint and make it shackly." To avoidthis, and to'reliev'e the connection 0, I form n notch,.f, in one part,and a corresponding projection, it, upon the other part, so that, whenthe two parts are open, as in iig. 2, the projectionon theone part willenter the notch or recess in the other part, and thus serve partially asa guide, and as a chief support for-the two parts in a proper position.i

It will be readily seen, by those acquainted with the n'a nufacture ofsuch articles, that other forms of irregularity upon the end of thejoint would produce thesame result. I show theform, as denoted in thedrawing, as being very simple, and ot' acheap construction, but do notwish to be understood as confining myself to any particular 'form forthe end of the two parts of the joint; but having fully described myinvention,

What I claim as new and useful, and desire to secure by Letters Patent,is-

. A stump-joint, consisting of the two parts A and B, hinged together bya connection, 0, pivoted to each ofthe parts, forming the; meeting-endsof the joint, of irregular form, the one corresponding to the other, soas to operate substantially in the manner specified.
